See Half-Inch Green. Prebloom SJS treatment more effective if applied in high volume spray. Severe SJS infestation may require insecticide spray against crawlers in summer.
Insect: Tarnished plant bug (TPB)
Suggested action threshold: 2 to 3 TPB damaged buds per 10-branch sample, or average of 5 to 8 TPB per white sticky trap between Green Tip and Pink.
